Data and models used within the hydrologic science community are diverse. New research data and model repositories have succeeded in making data and models more accessible, but are, in most cases, limited to particular types or classes of data or models and also lack the type of collaborative, and iterative functionality needed to enable shared data collection and modeling workflows. File sharing systems currently used within many scientific communities for private sharing of preliminary and intermediate data and modeling products do not support collaborative data capture, description, visualization, and annotation. This presentation will cast hydrologic datasets and models as “social …

International Congress on Environmental Modelling and Software
Nitrogen atmospheric deposition is known to severely impact ecosystem functioning by influencing soil biogeochemistry, nutrients balance and, consequently, tree growth, forest health and biodiversity. Because the ongoing global changes affect the ecosystem processes, climate change and atmospheric deposition must be conjointly taken into account to assess the evolution of forest ecosystem status over time. The general purpose of this work was to predict forest vegetation response to the combined impacts of nitrogen atmospheric deposition and climate change by using dynamic modelling approaches. The coupled biogeochemical-ecological model ForSAFE-Veg was first run to simulate this response on three well referenced studied sites …

Growth in World’s population, the expansion of human activities and the demand for land has and continues to damage the natural environment. Humans depend on the natural environment for essential life-preserving processes, for example food production. Damage to the environment has serious consequences for national (State) and human security and well-being. One concern is food security and, in particular, whether a growing World population will find enough food to eat. The consequences of using more land and resources to grow more food are an important area of research. The expansion of farming will leave less land for other important uses. …

International Congress on Environmental Modelling and Software
Calculating the hydraulic state, through and across elements such as pipes, valves and control devices is an important task in managing a water distribution network. Although hydraulic models are widely used by water utilities and engineers, they are governed by a huge number of uncertain parameters like the diameter and roughness of pipes, consumer demands, leakages and the internal state of valves inside the distribution network. In the past, extensive work has been done on the calibration of these parameters but the results are still uncertain. The objective of the research done as part of the French-German project ResiWater is …

Snow accumulation and melting are fundamental components of the hydrologic cycle in many water systems across the world. In such contexts, improving snow monitoring can be extremely valuable in a variety of operational contexts, such as avalanche protection, medium to long-term streamflow forecast, and drought risk management. Despite recent advances in environmental monitoring systems, continuous snow monitoring systems able to collect data at high spatial and temporal resolution are not well established yet. The unprecedented availability of user generated data on the Web is opening new opportunities for enhancing real-time monitoring and modeling of environmental systems based on data that …

International Congress on Environmental Modelling and Software
There is a lack of models to predict soil inorganic carbon (SIC) which are not only multipurpose, but can predict SIC in a variety of soils and materials. The importance of estimating SIC stocks is due to the large contribution they make towards total carbon in some soils. This paper proposes such a model which aims to account for the variance and geographical range of soils. As an example, one such use is the accurate prediction of passive SIC sequestration rates as this is currently a complex challenge, mainly due to environmental effects such as water, temperature and atmospheric CO …

In the frameworks of environmental management and computational sustainability, this paper aims at improving, in a cost-effective manner, the sustainability of existing drinking water production plants (DWPPs) via multi-objective constrained optimization (MOO). Specifically, the paper explores the ability of global sensitivity analysis (SA) methods to support MOO of DWPPs by means of a quick identification of a subset of the most sensitive decision variables from a large set, which leads to better quality solutions under limited time budget. To this end, the paper conducts a comparative analysis for this MOO problem of two major SA methods, namely Morris and Sobol’, …

Residual Soil Nitrogen Scenario Analysis Of Canadian Farmland Using A Canadian Agricultural Nitrogen Budget (Canb V4.0) Model, Jingyi Yang, Craig Drury
International Congress on Environmental Modelling and Software
A Canadian Agricultural Nitrogen Budget (CANB) model has been developed since 2002 to estimate Residual Soil Nitrogen (RSN) and N leaching loss across Canadian farmland. The current results showed that national RSN averages in Canadian farmland (annual N input minus annual N output) increased from 9.4 kg N ha-1 in 1981 to 23.6 kg N ha-1 in 2011 as mainly affected by the increase in synthetic fertilizer N usage and biological N2 fixation. With annual drainage, about 50 and 80% of residual soil N was lost in Central (Ontario and Quebec) and Atlantic Canada, respectively, through leaching and varying according …

Hydrologic modeling is essential for environmental, economic, and human health decision- making. However, sharing of modeling studies is limited within the watershed modeling community. Distribution of hydrologic modeling research typically involves publishing summarized data in peer reviewed journals, producing reports, or presenting at conferences. This narrow data distribution process limits interoperability, decreases transparency, wastes leveraging potential, and discourages detailed evaluation by other modelers. These limitations are also experienced beyond hydrologic modeling. For example, an economic analysis for nutrient trading may not be possible without access to detailed hydrologic modeling data. To address these issues, the Watershed and Economic Data InterOperability …

For environmental, ecological and human health sustainability, there is a great need to limit the structural dependency of agriculture on pesticides while, at the same time, maintaining satisfactory levels of production and farmers’ gross margins. A model was developed to explore the consequences of various management policies to contain blackleg on canola, on a long term basis. This model relies on the Graph-based Markov Decision Processes (GMDP) framework, that allows representing and optimizing sequential decisions under uncertainty, taking into account interactions between fields (spore dispersal). The objective of the study is to help better enforce management practices such as cultivar …

Integrating Human Agency And Ecosystem Services: An Abm Perspective On Food, Stefano Balbi, Ferdinando Villa
International Congress on Environmental Modelling and Software
Food is a primary provisioning ecosystem service. The concept of ecosystem services only focuses on the flow of services from nature to humans and doesn’t consider human flows, which include both the flows from human to nature (i.e. the co-production of ecosystem services or environmental pressures caused by humans) and human to human flows (i.e. social flows). Neglecting human flows is a main issue for modelling food provision within the ecosystem services framework, especially so under a food security perspective, where food access greatly depend on economic entitlements and social networks. We use the example of food security to provide …

Monitoring programs in Germany offer a large variety of data. On the one hand, these data are generated over many years in selected sampling areas; on the other hand, studies of monitoring take place in the context of research projects or other investigations. These data are often available in web-based information systems. Two databases will be presented with their potential for the interoperability with a (technical) platform for data of the chemical monitoring. The European project "Information Platform for Chemical Monitoring (IPCheM)" promotes networking of various existing databases and information systems with the goal of advancing the environmental data exchange …

Best management practices (BMPs) can be used effectively to reduce nutrient and sediment loads generated from point sources or non-point sources to receiving water bodies. Methodologies for optimal, cost effective BMP selection and placement are needed to assist watershed management planners and stakeholders. We developed a modeling-optimization framework that can be used to find cost-effective solutions of BMP placement to attain nutrient load reduction targets. The framework integrates the Soil and Water Assessment Tool (SWAT) watershed model, spatial representation of BMPs, an economic component, and multi-objective optimization routines in the R environment. The framework can be used to launch individual …

Crop models dynamically simulate nutrient and water cycles on a daily basis to predict crop growth and yield. They can be integrated into decsision support systems (DSS) dedicated to helping farmers improve their profitability and sustainability by pro-actively adapting their cultural practices (for example irrigation and fertilization). One key challenge is then the use of appropriate input data, and in particular of weather data: current weather data drive the simulation of the daily crop growth, seasonal forecasts are used to predict the yield at the end of the growing season, and both are elements on which farmers base their strategical …

We present a concept for a system to manage and distribute geo-referenced raster data from multiple possible sources on the institute level. The core concept is to centralize all import routines for data from different sources and formats, store the information in a common data format and distribute the needed information for research purposes upon request. By using hdf5 files, it can be assured that geo-spatial data is always kept in close connection with the corresponding meta-data. Furthermore this approach builds a technical basis for enhancing data fusion methods by allowing the use of common analysis routines, regardless of the …

What Is The Role Of Human Decisions In Restoring A Clear Lake?, Romina Martin, Maja Schlüter
International Congress on Environmental Modelling and Software
Human decisions affect and are affected by ecological systems in multiple ways. Natural resource modelling has commonly focused on the decisions of resource users or strategic planners. We argue that the dynamics of social-ecological systems (SES), however, emerge from multiple social-ecological interactions that are the result of decisions from different actors. As a first step towards incorporating this social complexity into models of SES, we developed a model that includes decisions by governance actors, ecosystem users and individuals that affect the state of an ecological system. We use the example of lake restoration, i.e. the ecological regime shift from a …

It is important to increase the resilience of rural landscapes in the face of global changes. It is widely recognized that integrated modeling is often a methodological choice to study landscape resilience because the task is often beyond the ability of direct, empirical studies. However, so far there has not yet been a systemized, critical review on methodological abilities current modeling approaches can have for supporting management for agricultural landscape resilience. This review study (i) highlighted the methodological abilities of integrated system modeling ideally needed for agricultural landscape management for resilience, (ii) reviewed strengths and weakness of common integrated modeling …

Severity-duration–frequency (SDF) curves of periods of rainfall deficits are useful tools for drought analyses. However, accuracy of these curves are affected by uncertainties associated with a number of factors including: (i) the choice of drought index, (ii) the sampling error due to the limited length of observation data, (iii) the effects of aggregation of data with respect to drought timescales, (iv) the selection of marginal probability distribution functions of drought severity and duration, (v) and the type of copula used to approximate the dependency between severity and duration. In this paper we assess the impact of these uncertainties on estimates …

A Framework For Developing Simple Adaptive Indicator-Based Water Treatment Decision Support Systems, Mohamed A. Hamouda
International Congress on Environmental Modelling and Software
A number of indicator-based decision tools have been developed to help select optimal water or wastewater treatment technologies. Water treatment is an inherently dynamic process that is influenced by constantly changing external factors, such as: deteriorating source water quality, changing regulations, and uncertain economic situation. Thus, decision support systems developed to select among alternative water treatment technologies should be adaptive to such changes. However, many of the developed tools still follow the traditional route of assigning fixed values and weights for the used indicators. Moreover, existing attempts to make the decision logic more adaptive often comes at the expense of …
